Useful resources to learn Java for free in 2023.
When it comes to programming, there is one language that has remained prominent, reliable and sturdy over the decades and that’s Java.
Java today is a bit like its original name "Oak" - while the name may have changed, the language remains as solid and steadfast as an old oak tree 🌳, providing a strong foundation for developers to branch out and create amazing software.
What is Java?
Java is a high-performance programming language and adaptable platform, initially developed by Sun Microsystems in 1995 to be portable across all devices. Its purpose was to enable developers to write code once and run it anywhere (WORA).
The unique aspect of Java's design lies in its object-oriented approach, which strives for minimal implementation dependencies so that pieces of code can function independently as reusable components.
Why is Java considered one of the most widely used programming languages?
There are several reasons why Java is widely used today. For starters, it has a vast ecosystem and an enormous community of developers.
Furthermore, from enterprise-level systems to portable devices, Java pervades various settings around the world.
Its compatibility with popular platforms such as Windows, macOS, Linux, and others has also made it a preferred programming language amongst developers worldwide.
The role of Java in the development of web and mobile applications
Java has played a crucial part in shaping the digital world, especially when it comes to web and mobile app development.
The presence of Java-based frameworks such as Spring, Java EE and JavaServer Faces (JSF) has given developers much-needed tools for creating applications that can scale well, and provide maximum security measures while being packed with essential features.
In terms of mobile use, Java's significant contribution to Android makes it the go-to language for developing apps on millions of smartphones and tablets around the globe.
The Benefits of Learning Java
Learning Java can unlock numerous career opportunities for newbie programmers.
From the finance and e-commerce industries to healthcare and gaming, there is high demand for skilled Java developers.
Yet, beyond just a promising career path, there are multiple benefits to pursuing this language, such as:
- Enhances problem-solving and critical thinking skills through its object-oriented programming (OOP) principles and structured approach.
- Promotes attention to detail with its strict syntax and error handling.
- Enables the development of robust and scalable software with a focus on performance, reliability, and security.
- Offers features like garbage collection, strong memory management, and built-in exception handling for stability and efficiency.
- Provides a vast ecosystem of libraries and frameworks that simplify complex tasks and accelerate development cycles.
